SDT/IMCS Sherlog Training

Introduction to the new SDT-IMCS hatch cover training

Following the launch of the new SDT Sherlog product range (Sherlog Cadet, Sherlog Mate, Sherlog Master function kits) in February 2013, there was a need to review certain parts in the existing SDT–IMCS training programme in order to accommodate for familiarisation training for the Sherlog Master.

Together with this review, the way of delivering the course has seen some drastic changes. In the first place, the equipment training is now given by means of a virtual Sherlog Master tool which allows the candidates to follow the correct measuring and operation procedures step by step. Once the basic familiarisation with the equipment is completed, the trainees are further trained by means of a virtual exercise which brings them on board of a vessel and where, through simulation, they are required to make several surveys themselves. The Sherlog Master reporter software allows candidates to get instant access to the survey report sketch and to learn from mistakes made.

Apart from the fact that this new approach allows for a much more in depth training in a safe and comfortable environment, it also does away with the safety and security problems related to attending on board of a ship in operation. So far a total of 7 well attended and successful “new” trainings have been organised.

Terms and conditions

SDT International S.A. organizes a series of training sessions to allow delegates to become "Certified Operator qualified for ultrasonic hatch cover tightness testing with the Class Type Approved Sherlog Master " in compliance with the IACS UR Z.17. Practical details of the SDT-IMCS Training Program, which is accredited by the Nautical Institute, can be found hereafter.

Training Program:

SDT International determines its training program in order to meet as closely as possible the industry's demand. Hence, the below listed training course dates and locations are subject to modification and depend on the number of the registered participants.

Upcoming training locations:



For the comfort of the trainees, and in order to ensure compliance with the accreditation standards, training courses will be organized in hotels of good international standard.

Training Session Agenda:

The training was developed in a way to cover all the required topics under IACS UR Z17 as much as possible, and yet to be concentrated in a 2 ½ day training course. Therefore SDT has decided to forward, upon receipt of the training fee, the complete syllabus of the training course by e-mail to each registered delegate. In addition to the training syllabus, each of the delegates will also receive the well-illustrated "Hatch Cover Inspections" book, published by the Nautical Institute in 2003 at the commencement of the training course. The purpose is to allow all candidates to become fully acquainted with the many subjects and issues covered by the training course, prepare themselves for the training and have relevant background information at hand during the execution of their day-to-day activities.
